Pylorus Ultrasound

Pylorus Ultrasound is an exam that obtains images of the pylorus with sound waves. Affected infants display symptoms of vomiting, dehydration and weight loss between the ages of two to eight weeks. The wall and length of the pylorus are measured by the sonographer. This measurement gives the radiologist important information to properly diagnose pyloric stenosis.

Procedure

The infant will lie flat or on their side on an exam table with the abdomen exposed.

A non-greasy gel will be applied to the skin during the exam.

The sonographer will use a hand-held transducer (probe) against the abdomen to obtain images of the pylorus.

The exam will be checked by a radiologist before the infant leaves the department.

The infant may be given water during the exam to obtain further information.

Preparation

The infant needs to be NPO (nothing by mouth) two to three hours before the scheduled appointment.

Arrive 15 minutes prior to your scheduled appointment with a prescription if your doctor has given one to you.
